I used to believe that some people were vegetarians because they were allergic to meat.
A childhood belief about dangerous food

others believed things like this
- When you are very poor you "can't make end's meat." End's meat is some sort of cheap very low quality meat.— Betty
- When I was six my sister told me Meat Pies were made from mashed up rats...to this day I can't eat a Meat Pie.— Jamie
- I thought vegetarians couldn't read Chicken Soup for the Soul. — Aretia
- my brother used to believe that Ground Chuck meat was actually groundhog meat. Anon
- I used to think I was allergic to spoons (what a spoon!)— Sally
- I used to believe that I was allergic to the sun, because whenever I looked at it, I would sneeze.— John 117
